There is a hygrometer and thermostat within the box. All was done by the fabricator of the custom humidor. The client purchased it from a company in Florida. I will check my files to see who it was. Not sure of the price of the unit. The frame was apx $500.00 installed by the finish carpenter. It needed power brought to the location. If you use any lighting, suggest LED from the outside.
